Let me put this way:
I usually download ISOs from BT with rates exceeding 1.5Mbps. (I'm on a
2Mbps/512Kbps line) My BT is upload is configured to cap at 256Kbps. (To
leave me some link space for my VPN connection.) Last ISO I downloaded
(FreeBSD) was downloaded at above 1Mbps sustained.
I've got a manually configured iptable firewall and my ISP *does* not
block BT ports.

However, I'm downloading x86_64 ISO at ~300Kbps (~150Kbps upload) and
the i386 ISO at ~40Kbps(!!!) (110Kbps upload).

BT is indeed slow.... and in my case, there's no problem between my CRT
and operator chair.
